For our end user it was a simple decision and now they are benefiting from lower running cost and lower carbon emissions.
£9,000.00 including heat meters and 1st year Maintenance.
Estimate payback of approximately 3 years to alternative oil fired heating system.
Temperature Control Limited provided the heat loss calculations using the Mitsubishi whole house and room by room calculation MIS3005 v4 which is the approved method by MCS best practice installation and commissioning procedures in order to design and build the heating system.
A Mitsubishi Electric Ecodan Air Source Heat Pump PUHZ-W85VHA2 with a 210l pre plumbed cylinder and new FTC5 control was used for heating and hot water of this new self-build.
Heat to the property was a split between UFH to the ground floor and radiators to the first floor with a design flow rate based on weather compensation of 45°C @-2°C ambient and 35°C @+15°C ambient.
Hot water will have a mean temperature of 40°C flow and once a week pasteurisation to 70°C.
